Abstract
A data transfer circuit that transfers a first kind of data stored in an external memory circuit includes: an internal memory circuit that is capable of, by an external circuit, writing and/or rewriting a second kind of data including information for one region as a transfer source in the external memory circuit and another region as a transfer destination in the external memory circuit; a transfer circuit that transfer the first kind of data; and a control circuit that makes the transfer circuit transfer the first kind of data stored in the one region to the other region based on the second kind of data.
Claims6
A data transfer circuit that transfers a first kind of data stored in an external memory circuit, the data transfer circuit comprising:
- an internal memory circuit that is capable of, by an external circuit, writing and/or rewriting a second kind of data including information for one region as a transfer source in the external memory circuit and another region as a transfer destination in the external memory circuit;
- a transfer circuit that transfers the first kind of data;
- and
- a control circuit that makes the transfer circuit transfer the first kind of data stored in the one region to the other region based on the second kind of data,
- a first data of the second kind of data including at least link information that links to a second data of the second kind of data, the link information including a link to image data for transfer upon completion of the transfer of the first kind of data,
- the control circuit controlling the transfer circuit based on the link information, and
- the control circuit receiving a trigger signal input, and controlling transfer timing of the transfer circuit based on the trigger signal input.
